Description arif 2009-11-30 10:05:12 EST
Description of problem:

krb5 1.7, as installed on f12, when used with an Microsoft AD server tries incorrect passwords multiple times. As AD account lockouts are often configure theis will lock a users account on the first incorrect password.

Version-Release number of selected component (if applicable):

1.6 is fine, 1.7 is broken. 

How reproducible:


Steps to Reproduce:
1. configure krb5.conf to use a AD server 
2. kinit <user>
3. Enter incorrect password
Actual results:

$ kinit user
Password for user@example.com: 
kinit: Clients credentials have been revoked while getting initial credentials

Now the account is locked.

Expected results:

$ kinit
Password for user@example.com: 
kinit(v5): Preauthentication failed while getting initial credentials

Probably a dupe of Bug #554351.

Yep, it's the same one alright.  It should be fixed in 1.7.1, which I hope to get into updates-testing today.

I think this bug can be closed; I haven't seen the problem since upgrading to the fixed krb package.

Alright, then.  Thanks!
